Slightly off topic: I went to download this and it said I needed iOS17. Out of pure curiosity what from iOS17 does it need? Apologies if it’s mentioned in the article, I just skipped ahead to final product.


Not off-topic at all, happy to answer!

- Map Annotations - SwiftUI Metal Shaders (for the CRT effect) - SFSymbol Animations

If I remember anything else I'll mention :)


It is mentioned in the article -- the app uses new APIs in iOS 17 for map annotations.


Correct, also SwiftUI Metal Shaders (about which I've written an upcoming article) and SFSymbol animations
